电催化全解水是开发绿色能源和促进可持续发展的重要途径,主要涉及OER和HER的两个关键电催化过程。由于全解水的动力学缓慢以及存在热力学短板等问题,因此需要高效的OER和HER电催化剂来减少过电势,加快全解水的反应速率。作为最有前途的候选者之一,NiCo2S4(NCS)由于其低成本,高催化活性和增强的稳定性而引起了极大的兴趣。NCS具有Ni2+/Ni3+和Co2+/Co3+的氧化还原电对,是OER的有效活性中心。此外,大量研究表明NCS与其它导电基材(例如石墨烯,碳纳米管和其它过渡金属硫化物)的复合材料可增加暴露的活性位点并增强OER/HER反应动力学。然而,尚未系统地研究与NCS与N,S共掺杂的还原氧化石墨烯复合对全解水电催化性能的协同作用。因此,合成具有大量活性位点的NCS/NS-rGO复合材料并阐明协同作用对其电催化活性和稳定性具有至关重要的意义。
石河子大学陈龙团队报道了一种以硫脲作为N、S源和沉淀剂,通过一步水热法合成的分级多孔NCS与N,S共掺杂还原型氧化石墨烯复合的新型材料(NCS/NS-rGO)作为一种全解水电催化剂。由于N和S共掺杂的rGO的独特微观结构,由纳米棒组装的NCS微球均匀地锚定在NS-rGO的表面上,两者的结合可以有效地改善NCS/NS-rGO的电导率和电子结构,并提高其电子传输能力和电催化性能。NCS/NS-rGO在碱性和中性电解液中显示出优异的HER和OER催化性能,并且系统地阐明了NCS/NS-rGO的电催化机理。这些结果为开发双功能全水解电催化材料提供了新的研究策略和理论基础。综上所述,NCS/NS-rGO优异的电催化活性对于开发中性和碱性系统中经济可行的全解水具有重要意义。
